The IRS provides the following advice:
"If you have not received your W-2, follow these three steps:
Contact your employer first. Ask your employer – or former employer – to send your W-2 if it has not already been sent. Make sure your employer has your correct address.
Contact the IRS. After February 14, you may call the IRS at 800-829-1040 if you have not yet received your W-2. Be prepared to provide your name, address, Social Security number and phone number. You should also have the following information when you call:
- Your employer’s name, address and phone number;
- Your employment dates; and
- An estimate of your wages and federal income tax withheld in 2012, based upon your final pay stub or leave-and-earnings statement, if available.
File your return on time. You should still file your tax return on or before April 15, 2013, even if you have not yet received your W-2. File Form 4852, Substitute for Form W-2, Wage and Tax Statement, in place of the W-2. Use the form to estimate your income and withholding taxes as accurately as possible. The IRS may delay processing your return while it verifies your information."
